The group says those symptoms can include, in the case of deep vein thrombosis, swelling, pain or tenderness akin to that from a charley horse, discoloration of the skin, and skin that’s warm to the touch.

In the case of a pulmonary embolism, symptoms may include sudden shortness of breath, stabbing pain in the chest (particularly with deep breaths), rapid heart rate, and coughs (particularly with bloody mucus).

Athletes may face particularly high risk of clots due to sitting for long periods of time on frequent flights or bus rides between games as well as dehydration, hard contact to the legs, and surgeries to repair injuries.

African-Americans, like Bosh, are also at greater risk — 30 to 60 percent greater, according a 2016 — than other ethnicities.

Other factors that can increase risk for athletes and nonathletes alike include cancer, obesity, pregnancy, hormone-based birth control methods, and family history.

Height as a risk

The lead researcher of the new study, Dr. Bengt Zöller of Malmö University Hospital in Sweden, said in a statement that height should now be added to that factor list and included in risk assessments.

He speculated that the simple fact that taller people have longer veins and their blood has farther to travel may play a role in explaining the increased risk his team found.

“It could just be that because taller individuals have longer leg veins there is more surface area where problems can occur,” he said. “There is also more gravitational pressure in leg veins of taller persons that can increase the risk of blood flow slowing or temporarily stopping.”

The best way for taller people to reduce their risks may be to avoid the other risk factors — ones they can control — as much as possible.

“We have no control over our height, but we certainly can all take the appropriate measures in making healthy lifestyle choices to reduce the risk of various conditions,” Zöller said.

Bosh, now a spokesperson for the blood thinner Xarelto, found out about a blood clot in his leg while at the All-Star Game festivities in 2016.

He spent the next six days in a hospital in Toronto.

“And then came not being able to play the game I love, the game that I’ve spent a lifetime working to master and evolve with and find success in,” he wrote in a goodbye letter to Miami fans in July.

The Heat kept Bosh off the court — over his objections — over concerns that due to his blood thinners a blow to the head or other hard contact could be debilitating or deadly.
